Check the bounce on your ar.
And mat and record weight could help.
I use a bren and cork/lead mat on my ar's.
I have a 700g record weight, but the springs cant support it.

Hi Vince.

Nice you found the problem with the Pearl.

I think that TT is a fine animal indeed.
Bit of tune-up...
...BOOM !!!!

Looking forward to your loading experiments.

A switch with 900 Ohm combo's of series / parallel looks like the way we gonna go here for now.
Just drawing up the switching schematic & waiting for switches to arrive !

Audio nirvana by Christmas ?
( could take a bit longer here ! )

Cheers.

Si.

They have springs and everything else. I'm just wondering what is the proper setting for the springs?

Dave is a good guy too. I got my matt and the pully for one of my XA's from him.
He know his ar's too.

Spring setup is very interesting. I found that learning what and why you are doing makes it easier.
Marc wrote up a bit of info on this on audio karma.
If I can find it ill post a link.

Ill have to see if I can find marc's contact info. He could sum it up better.

Not to hard, takes time to do it right.

Ill see what I can dig up and send you.

The manual downloaded frm Vinyl Engine doesn't help with spring adjustment all that much.

Thx

Vince

Hi Vince.

This is getting good !
So many upgrades...so quick !

Sounds like with Pearl & springs sorted...
...could be perfect for DL-110 loading experiments.

Great christmas present !

Cheers.

Si.

I can highly recommend those parts for AR tables. I also have an AR The turntable, but all that's left is the wood part and the metal top plate.

Improved springs with extended studs like Vinylnirvana has are a large improvement. The first mods I did were to buy the delrin armboard, to which I mounted an Infinity Black Widow Tonearm, extended springs and studs and the lead mat. These changes made a huge difference. Going on with the Terpolymer subchassis, Improved bearing/spindel, delrin inner platter and acrylic outer platter made even greater differences. The periphery ring/clamp and Bren1 weight finished it off performance wise.

I took the platter, lead mat and Bren1 to a friend of mines home to try on his AR, and the platter and mat alone bottomed out the suspension! Definitely need the stronger springs and extended studs here! Plus, most of these springs are now just flat worn out.

Make no mistake, these improvements will rock this table into very high performance territory, no minor tweeks are these!
